`Iii/renover) EXTENSION-'rimane The 'Schedule `:referred to in these 4LetterePatent and making part of the Same To allwhom tt 'may concern Be it known that we,'WILLI.AM REIGHENBAGH and FRETRIGH RosoHIiIANTzKY, bothof Chicago. in the county of Cook, and State vof Illinois, Ahave invented certain Improvements in Extension-Tables, of which the following is a speciiication, reference heilig had to the accompanying drawings.

Our inventiouconsists in a novel manner of con structing three frames or sections provided with suitable legs, and connecting them by a'series of crossed levers in suc-h manner that they may be moved from or towardA one another without being disconnected; and arranging, `in connection with the above, a seiies of leaves hinged 'to the middle frame or sectioii, so, that they may be extended, and supported by` the cross-levers and the outside 'or ,end traine-s, as hereinafter described. .i

Figure l is a. side elevation of our table with one side or section extended and the other closed; and

Figure 2 is a bottoni plan view of the' saine.

In constructing our table we first make, the central` or main body A, consisting of two parallel side pieces a, haring two legs, b, secured rigidly to them at the middle, and 'a 4rectangular nently on top..

Onr the inner sides of the side-pieces a we fornigrooves or rabbets, d,'and between the said pieces mount .two crosshars, e, with their ends resting in the i'abbets, so tlielcrossebars may be moved to the middle or out to the ends of the side pieces, as shown respectively by the left and right-hand bars in iig. 2 pieces bein g broken away to show top, c, attached perinathe rabbet.

i We next construct `two frames, O, each provided with two rigid legs, f, and two side rails, ln, far enough apart to pass outside ofthe sides a ot' frame A. These trames we place one opposite each end offi'anie A, and-connect each ofthe frames Gwith one of the cross-bars e, by'ineans of a series of crossed levers D,

commonlyy known as lazy tongs, or J acohs ladders, as shown in figs. 1 and 2; the upper sides of these levers coming in line with the under side of the stationary top c. Y

When thus connected and arranged, the frames C may be closed up against and around frame A, as on the left hand of the drawing, or drawn out a consideri able distance from thek same, as shown on the right side of the drawing, the system of levers serving to Vkeep the frames inline, and ,to oonneotthem in suoli manner that they support one another in an upright position.

The top c we make of snchglength that, when the franies O are closed up againstthe main frame, the

.lo each of these overlianging ends of the top c, we hinge a series of leaves or boards, E, hinged to one another, as shown iii both figures, which leaves, when the frames are closed, may heV folded up conipactly against the under side of the top, and then he supported in that position by sliding hai-st' passing through the legs f, as shown on theleft; or, when the frames C are extended, the leaves maybe unfolded and ex- *tended on top of the same, so as to form a continuation or extension of the the top c, -shown on the right of the figures.

When the table is closed and. it is desired to extend lit, the bars t' are shoved inward, so as to release the leaves, which are'tlien turned over upon the top c, as shown on the iight; the frame C is then drawn outl .the proper distance, and the leaves folded out upon the saine, `shown in iig. .2, and in dotted lines in tig. 1. i

In'closing the table the operation is merely reversed, the leaves heilig tirst folded upon the top o, the frame closed, the leaves th'en turned down under t-lie'top, and the bars t drawn out under them. v

W'hen a table of medium length is required, one frame is extended; but when a table of still greater vlength is desired, both frames are extended.

cheap, and simple table, that Inay be quickly and easily transformed into a small space or extended yto a great length, without detacliing any of the parts or pieces.

Having thus described our-invention,

What we claim is- A table having the central part A, with the exten'- ysion-leaves E and the extension-frames C D. constructed and arranged to operate substantially as described.
